Grilled Sweet Potato Wedges Recipe

Place potatoes in a large saucepan and cover with water. Bring to a boil. Reduce heat; cover and simmer for 4-5 minutes or until crisp-tender. Drain; pat dry with paper towels. Sprinkle potatoes with garlic salt and pepper. Grill, covered, over medium heat for 10-12 minutes or until tender, turning once. In a small bowl, combine the mayonnaise, yogurt and seasonings. Serve with sweet potatoes.
